Singapore Airlines Business/First Class Upgrade Below are three easy ways to upgrade your Singapore Airlines ticket to premium economy, business class, or first class. The Singapore Airlines policy allows ticket holders to upgrade to Business Class or Premium Economy if there is space available. Members of Velocity can use their points for upgrades to premium economy or award seats in Business class on all Singapore Airlines routes excluding those to and from China and Hong Kong. In addition to the already reduced prices of Lite fares, award tickets can be upgraded to the next cabin level higher using KrisFlyer miles (or two cabins from Economy class to Business class on planes that have Premium Economy). As you can see, the value of using KrisFlyer miles to guarantee a business class seat after purchasing a full-price Economy ticket on an upgradable fares code is reduced in both scenarios, with an estimated value of around 1.3 cents per mile after factoring in the miles you would have earned for a basic ticket. From Singapore, you can fly to London or Paris in business class for 65,000 KrisFlyer miles one way in flexible fares or 80,000 miles in economy standard tickets. This is somewhat less than the 85,000 miles required for a direct Business class award. To be eligible for an award upgrade from Economy Standard, your Singapore Airlines or SilkAir ticket must be booked as an M, H, or W fare. You can use miles or points to upgrade your ticket either at the time of booking or after purchasing an economy ticket through the airline's online reservation system. Buying a ticket in business class and Singapore Airlines Upgrade. First or business class is the most cost-effective option. If you want to upgrade to business or first class, you can try your luck at an auction with several airlines. Some upgrades are mixed-itinerary, meaning that if your flight has a layover, you may be in economy on one leg and business or first on the next. This can be a bad deal if the leg on which you are upgraded is shorter. Despite the preceding, no refunds will be given for the cost of the upgrade or the miles used to purchase it if the passenger reeboks into a seat of the same or higher class than the upgraded ticket on the same aircraft or on a different flight. For the avoidance of doubt, the purchase of an upgraded seat does not result in the accumulation of KrisFlyer miles, elite miles, PPS values, or miles on any other KrisFlyer Partner Airlines. If you paid for a premium economy upgrade and then got bumped up to business class, that's not allowed because mySQupgrade only allows one upgrade per segment (however, as shown in the above screenshot, an economy passenger can purchase an immediate Business Class Upgrade). Another option is to just pay the fare difference to upgrade to any fare class. However, not all tickets can be upgraded, so don't expect that if you buy a cheap fare.
